Great kit for kids!.
My 2 year old son loved watching his caterpillars emerge and become butterflies! He loved feeding them fruit, and setting them free in our yard. Unfortunately not all of them survived(3 out of 5), but I attribute that to the Georgia heat during the shipping process, and definitely recommend expedited shipping if you live in a hot area. Will be ordering the refill kit soon, with expedited shipping of course.

Wonderful.
My wife and daughter passed recently, they were both butterfly lovers. My daughter got this for me for my birthday. It was amazing watching the transformation!! All ten painted ladies emerged over about a three day period!!! All ten!!! We then took them to the cemetery and released them. It couldn't have been more perfect.

Easy and Fun!.
PROS: 5 alive & healthy caterpillars. All turned into butterflies and were released successfully. Children and parents enjoyed watching them grow and transform so quickly! Fairly easy to care for. Beautiful butterflies!!!
CONS: The "meconium" or red liquid that is expelled when the butterflies emerge from the cocoons. There was A LOT and it was pretty gross. Running down the mesh of the habitat and looks like blood. Could be concerning for younger kids.
Also was a lot harder to remove the silk (frass) than the instructions explain. The silk is fairly thick and sticky. It started pulling cocoons very hard. Had to clip silk off with scissors for fear of yanking cocoons off of paper disk.
Would definitely give it another try now that we know what to expect. It was a bit more difficult than instructions lead you to believe, but still completely worth the end result!
